ABSTRACT:
Moist bulk coal is supplied into a fluidized bed drier into which is introduced a first heat carrier gas to thereby dry the moist coal to form dried coal. The dried coal is discharged from the drier and is transferred to a generally horizontal bulk material conveyor. A second heat carrier gas is injected through the bottom of the bulk material conveyor, thereby transporting the coal generally horizontally and preheating the coal to form preheated coal. The preheated coal is then discharged from the bulk material conveyor and is filled into a selected charging opening of a coke oven battery.
